A novel stereotactic needle placement technique enables precise retrobulbar anesthesia. This CT-guided method significantly reduces the risk of ocular and optic nerve injury during local anesthetic injection.

Area of Science:

  • Ophthalmology
  • Neurosurgery
  • Medical Imaging

Background:

  • Retrobulbar anesthesia is crucial for ophthalmic procedures.
  • Traditional injection methods carry risks of ocular injury.
  • Need for enhanced precision in anesthetic delivery.

Purpose of the Study:

  • To introduce a CT-guided stereotactic technique for retrobulbar anesthesia.
  • To evaluate the safety and precision of this novel method.
  • To minimize complications associated with retrobulbar injections.

Main Methods:

  • Utilized a CT-guided stereotactic device for needle placement.
  • Performed precise intraconal injection of local anesthetics.
  • Focused on stereotactic accuracy for reduced tissue trauma.
